‘Every team does it’: How World Cup sides thwart opponents’ spy efforts

As the FIFA World Cup 2026 approaches, teams are increasingly concerned about spying tactics employed by rivals. The U.S. men’s national team recently encountered a unique challenge at their training base in Irvine, California, where a giant balloon, part of the Great Park’s attractions, could provide an aerial view of their practices.

The balloon looks like a massive mandarin orange and rises to heights of 400 feet. With such visibility, many players and coaches are wary about being observed during their training sessions. This concern about spying isn’t uncommon in soccer, particularly around high-stakes tournaments. Recent incidents, including a drone being neutralized over South Korea’s session and jokes from U.S. coach Mauricio Pochettino about seeking out observers, highlight the ongoing issue.

Spying in Soccer: A Widespread Practice

U.S. midfielder Tyler Adams noted the prevalence of spying, saying, “Every team does it,” which reflects a broader reality in the sport. The art of espionage in soccer has numerous examples, from Southampton’s recent troubles with spying on opponents to the infamous telescope incident involving a Swedish scout during the 2018 World Cup. Even in more casual environments, teams remain alert, as illustrated by a Canadian staff member caught watching a U.S. scrimmage in 2021.

Spying is not just limited to professional leagues or critical matches; teams often take precautions for practice sessions as well. This includes conducting sweeps for hidden cameras, which has led to surprising discoveries, such as GoPros found in the Azteca stadium. The paranoia surrounding these practices creates a culture wherein frequent measures are necessary to maintain privacy.

The Reality of Surveillance

Various coaches have shared anecdotes about spying. Marcelo Bielsa, a renowned Argentine coach, famously admitted to spying on every opponent in 2019. While technologies like drones have modernized the approach, it’s clear that the tactics have been part of the game for a long time. The U.S. team has strict protocols, including familiarizing themselves with stadium layouts to identify potential surveillance equipment.

As teams gear up for the World Cup, FIFA promises robust security measures around training sites. Yet the overarching question remains: Does spying yield significant advantages? Tactical nuances can be observed, but many argue that a team’s strategies and player tendencies are often already known from past performances.
